I have the 240sx calipers with the the ZCD adapter plates. You can email Matt and he can tell you if the brackets are the same. At one time they sold both conversion kits.

I still think there possibly is a dirty ground problem

@SteveJ Maybe stepping out a bit but could this possibly be a dirty ground issue somewhere in the circuit?

IMHO time to pull out the multimeter

Power Brake Exchange is a great company that has terrific customer service. Thought the booster they rebuilt for me was not working correctly. They had me ship it back at no charge. Checked it out and after it was all said and done I had installed the check valve backwards. On the 78 280 the arrow points towards the intake. I had it backwards. Long story short the booster works perfectly.🤦‍♂️🤦‍♂️🤦‍♂️

Wow, that was 9 years ago

Just to confirm by the pic the black color coat p/n is 15013. Correct. Thank you for posting. Did you pick these up from a PPG distributor? Looks Fantastic!

There are folks here on the forum that have tested factory ECU’s and have them as spares. As far as the fast EFI system I’ve heard very little other than a friend on the forum tried it and it did not go well for him. I would reach out and see what you can find here on a tested ECU that someone has in their stash. Again the longevity of a replacement is hit and miss but I would definitely try that first IMHO.

Pics?

A little pricey. Paid $1100 for mine

My stroker has the diesel crank. Came out of the “Patrol” in New Zealand.

I get these periodically. There’s a whole list of things normally.

Possibly it’s loose up front?

Sorry @Mike I’m not on facebook

Was looking at the pic @siteunseen posted

Looking on the wrong side IMO. See the splines for the steering shaft?

1979,80,and 81 have verticle mounting. 82,83 horizontal.

@Terrapin Z

No

That particular distributor is the same one they sell on EBay. Two lead hook up. Red positive side of the coil, black negative . No ballast resistor. Everything is internal and as you can imagine not very well made but will possibly provide hints.

You are not going to uncover anything until the head is removed IMO. If you don’t have a competent machine shop in Panama I’m sure there’s a member on the forum that can recommend a shop here in the states closer to you where it can be disassembled and diagnosed.

Were the guides and seats replaced during the build to handle unleaded fuel

From past experience with what you are dealing with is the 3:90 ratio the engine will run at 3k rpm on the highway between 60&65 mph. 3:73 is probably optimal if you want to bring it down a bit. Although getting to that speed the 3:90 gets you there quickly.

View Advert 1978 280Z Door jam switch grommets Car is finally in the body shop and moving along nicely. They haven’t removed the switch assemblies yet but we’re concerned about the grommets by removing them without destroying them. With that in mind I am looking for another set in good condition. An option was to tape them off but I would rather it have a cleaner look. Switches aren’t necessary but will buy them as a set if needed. Pic provided by @SteveJ for reference. Thanks in advance.
